    AQA GCSE · Question 14.3 · Fundamentals of computer networks

    Give three advantages of using a wireless network instead of a wired network.

    How to approach this question

    Think about the practical aspects of setting up and using a network. What are the benefits of not having physical cables? Consider user movement, setting up the network, and adding new computers or phones.

    Full Answer

    1. **Increased Mobility/Convenience:** Users are not tied to a specific location by a physical cable and can move around freely within the network's range while staying connected. 2. **Easier Installation/Reduced Clutter:** No need to run physical cables through walls and ceilings, making setup quicker, cheaper in some cases, and resulting in less physical clutter. 3. **Easier to Add New Devices:** New devices can be added to the network easily without needing a physical port or a new cable; they just need the network credentials.
    Wireless networks (like Wi-Fi) offer several key advantages over traditional wired networks (like Ethernet). 1. **Mobility and Flexibility:** The most significant advantage is that users are not physically tethered to the network by a cable. This allows them to work from anywhere within the wireless signal's range, promoting flexibility and convenience in homes, schools, and offices. 2. **Simplified Installation and Cost:** Setting up a wireless network can be simpler and more cost-effective than a wired one, especially in existing buildings. There is no need to drill holes or run extensive lengths of physical cable through walls and ceilings, which can be time-consuming and expensive. 3. **Scalability:** It is generally easier to add new users and devices to a wireless network. As long as a device is within range and has the correct security credentials, it can connect. In a wired network, adding a new device requires a spare physical port on a switch or hub, and a cable to connect it.

    Common mistakes

    ✗ Stating disadvantages of wireless (e.g., "slower speed", "less secure"). ✗ Vague answers like "it's better" or "it uses Wi-Fi". ✗ Listing the same point in different ways (e.g., "no cables" and "less clutter" might be considered one point).
